IMPROVEMENT IN APPARATUS FOR G-NIEIRAI'ING- CARBONIC ACID.`

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern and exact4 description thereof, referencebeing had to the accompanying drawings and to the letters of referencemarked thereon making a part of this specification. f

The nature of my invention consists in the attachnient of a tumbler orhollow cap to carbonio-acid gas or other generators, for the purpose ofpreventing the compound from passing over into the washerY by the forceof gas.

In order to.l enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring tou the annexed drawings whichrepresent a side view of a generator, part in section', with my tumbleror cap attached thereto.

In all generators" for manufacturing carbonio-acid gas, soda,marble-dust, and Whiting are used in combination with oil of vitriol.This compound lbecomes thick, and is thrown against the sides of thegenerator, lling up (without great care) the space for the gas to passover into the washer, therefore, when the gas is let onto the beer orsoda-fountains from the washer, the gas in the generator must force thecompound into the mouth of the pipe over into the cooler or washer,thereby filling it up at the bottom and causing the water to rise in thewasher till it reaches the gas-cock, when, on letting on the beer orsodafounts, what should be pure gas, water is taken in impregnated withmarble and acid, destroying the beer or soda and making it unfit foruse.

To obviate this diflicnlty is the object of' my invention.

In the annexed drawings- A represents the usual gas-generator, having anagitator revolving within it.

On the side of the generator is au opening having a flange or colla-r,a, projecting on the outside around the same.

On this collar is screwed a' tumbler or hollow cap7 B, forming achamber, C.

The pipe for conducting the gas from the generator to the cooler orwasher is screwed on at the top of this cap or tumbler. This preventsthe compound 4from clogging up said pipe.v

l The tumblerB can readily be taken on" to clear the generator ofincrustation or any thing that may prevent the generator' from workingin a proper manner.

Having thus fully described my invention,

IVhat I claim as new, and vdesire to securel by Letters Patent, is-

In combination with a carbonio-acid gas or other generator, a tumbler orhollow cap attached to the generator in any suitable manner,substantially for the purposesherein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of February, 1870.
